Technical Field

The invention belongs to the technical field of steel tube towers, and particularly relates to a novel steel tube tower.

Background

The steel-pipe tower plays important effect at transmission line erection in-process, transmission line generally connects on the horizontal pole at steel-pipe tower top, supporting role to the circuit through the horizontal pole, realize long distance erection, because transmission line transmission's voltage is higher, so general steel-pipe tower height is all higher, the cross street area is less, this makes and becomes very difficult when overhauing the operation to the circuit at steel-pipe tower top, traditional steel-pipe tower only has one section cat ladder, finally still must realize the maintenance earlier through the fixed between the waist, it is very inconvenient, and dangerous.

Disclosure of Invention

The invention aims to provide a novel steel pipe tower which is simple in structure, convenient and quick to maintain.

In order to solve the technical problem, the invention provides a novel steel pipe tower which comprises a rod body, a ladder stand and a cross arm, wherein the cross arm is arranged at the top of the rod body, a fixing plate is arranged in the middle of a cylinder body, the top of the ladder stand is hinged with the fixing plate, a fixing block which is convenient for being held by hands and being stepped on by feet is arranged beside the fixing plate on the rod body, a positioning ring is arranged at the bottom of the ladder stand, a positioning piece is arranged at the position, located at the rotating positioning ring, of the rod body, and the positioning piece fixes the positioning ring when the ladder stand rotates to the.

In order to facilitate the positioning of the crawling ladder, the crawling ladder is improved in the invention that the positioning piece comprises a positioning block, a positioning hole is formed in the rod body corresponding to the positioning ring, the positioning block is arc-shaped, an arc-shaped channel matched with the positioning block is formed in the rod body, a clamping position is arranged on the lower side of the positioning hole, and a return spring is connected to the positioning block.

In order to facilitate maintenance, the invention has the improvement that the positioning hole plate is also provided with a maintenance hole.

In order to facilitate the fixing of the ladder stand, the invention improves that the bottom of the ladder stand is also provided with a hoop.

The improved hoop comprises two hooping pieces, wherein the connecting parts of the hooping pieces are provided with bolts and nuts, and the hooping pieces are fixed through the bolts and the nuts after bypassing the rod body.

The invention has the beneficial effects that: the novel steel pipe tower of structure is through can overturning the cat ladder from top to bottom, can relax fix at the highest position, compares with traditional safety belt, and safe and reliable more of cat ladder, setting element and the being connected of holding ring are fixed firm, and the maintenance personal can be convenient scrambles the assigned position and maintains.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to the attached drawings 1-5, the invention provides a novel steel pipe tower which comprises a rod body 1, a ladder 2 and a cross arm 3, wherein the cross arm 3 is arranged at the top of the rod body 1, a fixing plate 4 is arranged in the middle of the rod body 1, the top of the ladder 2 is hinged with the fixing plate 4, a fixing block 5 convenient for hand holding and foot stepping is arranged beside the fixing plate 4 on the rod body 1, a positioning ring 6 is arranged at the bottom of the ladder 2, a positioning piece is arranged at the position of the positioning ring 6 of the rod body after rotation, and when the ladder 2 rotates to the top of the rod body 1 through the hinged part, the positioning piece fixes the positioning ring 6.

Because the height of steel-pipe tower is generally than higher, can certainly not reach cross arm 3 through cat ladder 2, on the one hand be in order to prevent that other people from climbing the steel-pipe tower and causing danger, on the other hand is because cat ladder 2 is too long the length intensity is not enough, in this embodiment, the maintenance personal climbs the top through cat ladder 2, then direct one hand grips fixed block 5, fixed block 5 is stepped on to the other foot, later the rethread other hand is with cat ladder 2 through the hinge rotation, cat ladder 2 after the rotation passes through the setting element of holding ring 6 with body of rod 1 top fixed, later, the maintenance personal continues up through cat ladder 2 and climbs and can reach cross arm 3 and maintain.

In this embodiment, the positioning element includes a positioning block 7, a positioning hole 8 is provided at a position corresponding to the positioning ring 6 of the rod body 1, the positioning block 7 is arc-shaped, an arc-shaped channel 9 adapted to the positioning block 7 is provided in the rod body 1, a clamping position 10 is provided at a lower side of the positioning hole 8, and a return spring 11 is connected to the positioning block 7.

Referring to fig. 4 and 5, after the positioning ring 6 of the slide is inserted into the positioning hole 8 and abuts against the driving end of the arc-shaped positioning block 7, the arc-shaped positioning block 7 moves on the channel 9, and the other section of the arc-shaped positioning block 7 is inserted into the positioning ring 6 and is clamped with the clamping position 10 on the lower side of the positioning hole 8, so that when the slide is released, the positioning block 7 cannot move due to the restoring force of the spring due to the outward pulling force of the slide, and meanwhile, the positioning block 7 limits the positioning ring 6 from leaving the positioning hole 8.

After the maintenance is finished, the maintenance personnel returns to the fixing block 5, then the ladder stand 2 is slightly moved inwards, namely the positioning ring 6 is separated from the positioning block 7, at the moment, the positioning block 7 is returned from the channel 9 due to the restoring force of the restoring spring 11, and the ladder stand 2 can be separated from the positioning hole 8.

The height problem can be realized through a simple mechanical structure, the danger of adopting other safety bags is prevented, and the structure is simple and the effect is good.

In this embodiment, the positioning hole 8 is further provided with a maintenance hole for facilitating the replacement of the spring and the positioning block 7, but the hole is generally closed to prevent the rain from washing, which is not shown in the attached drawings.

In this embodiment, 2 bottoms of cat ladder still are provided with the hooping ring 12, after cat ladder 2 upwards buckles, fix cat ladder 2 on the body of rod 1 through the hooping ring, only draw the schematic diagram in the drawing, the structure is fixed through bolt and nut in the middle of two treasured hoop pieces, adopt ordinary staple bolt can.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
